Yamaguchi, S; Iwamoto, K

An intake system is described for connecting a carburetor and a combustion chamber of internal combustion engines. The system has a cylinder head, an intake port provided in the cylinder head, an intake valve located in the intake port and an exhaust manifold communicated with the combustion chamber. At least two intake passages are provided to join together at that part in the intake port which is immediately before the intake valve. One of the intake passages passes through the exhaust manifold, whereby the atomized fuel particles in an air-fuel mixture to be sucked in the combustion chamber can be positively vaporized without accompanying high temperature rising of the mixture.
